setcookie() 'samesite' option bugging

[Heraes-git]

From manual page: https://php.net/function.setcookie

---

This works :

$cookie_options = array('expires' => $max_expiration, 'path' => '/', 'domain' => '', 'secure' => false, 'httponly' => false);
setcookie("Sondage01", $cookie_value_string, $cookie_options);

This doesn't work :

$cookie_options = array('expires' => $max_expiration, 'path' => '/', 'domain' => '', 'secure' => false, 'httponly' => false, 'samesite' => 'None');
setcookie("Sondage01", $cookie_value_string, $cookie_options);
